Metro fibre - Ghosted Customer service

I am an existing metro fibre customer for over 4 years, however for the past 4 months their services has moved from 4 to negative zero. They don't follow up on customer complaints, respond to emails and Facebook page massages. My house has been without internet for over 2 weeks, I have sent emails , and Facebook messages and my complaint just landed on someone who cares less about the service that I am paying heavy amount of money for under this current economic challenges.
